APPARATUS ron HEATING, COOLING, AND VENTILATING BUILDINGS.

Specification of Letters Patent.

Patented Jan. 24:, 1911.

Application filed October 12,1907, Serial No. 397,058. Renewed September 28, 1910. Serial No. 584,310.

a construction whereby the temperature of the air in the space between the double walls of a building may be raised or lowered; second, the provision of means for circulating air through the rooms-or chambers of the building; third, to afford means for the inlet of air into the air space between the walls via the heating or cooling means; and, fourth, to produce a regulatable air outlet from the air space between the walls.

With the above and other objects in view,

my invention consists in the novel features and constructlon, and the combination and arrangement of parts hereinafter more specifically described, illustrated in the drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail ref.- erence is had to the accompanying drawings forming a part of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views, and in which- Figure 1 is a vertical section. Fig. 2 is a sectional view on line 22 of'Fig. 1. Fi 3 is a detail view of a gable end of a building with parts broken away. Fig. 4 is a perspective view of a length of a hollow binding wall plate. Fig. 5 is an enlarged perspective view of an air register.

One embodiment of my invention is described as follows: The Fig. 1 shows a section of a building with means on the lower floor for changing the temperature of the air, means for the introduction of the air ultimately into the air (space between the walls of the structure, and devices for the circulation of the air and its final passage out of the building. The reference numeral 8 denotes the outer wall of the building, and

9 indicates the inner wall, while the air space between the two walls is represented by the reference character 10. One means for changing the temperature of the air which enters through inlet '12, is the hot alr furnace 11, with its hot air pipes 13 communicating with the air space 10. It will be obvious if the air in the air space'lO surrounding the rooms or chambers is heated, the heat of the rooms will be raised. Air may be let into the air space 10 "throu h inlet pipe 14. The air reglster 15 near e floor, and the register near the ceiling 16, afford means to controlthe circulation of air through the rooms or chambers, by op-' erating the dampers 25. The reference character 17 denotes the hollow top wall plate, and 17 the air space in the same. The ventilating chimney 18 is controlled by the pivoted damper19, operated by cords 20. The lateral openings 21 permit the escape of air from the space 17' and the air space 10. Preferably a wire screen 24 is placed in eachregister. It will be noticed the skirtfportion 26 of the register box is of'greater dimensions than the screen end. The numeral 23 represents a tie-block at inter a.s to Lind the outer and inner walls together. a

It is preferred to make each gable end of the building .as shown in Fig. 3, but ,it will be apparent my invention Will be operative with only one such gable end.

The operation of my improvement will manifest on referenceto the drawings and the foregoing description.

The usual dampers 1n plpes 13 will control the inflow of air into the air space 10.

If instead of heat in the apparatus 11 there is employed means for lowering the temperature of the air, and the draft damper 19 is open, the cool air will fill the air space 10, and ultimatelythe air space 17. If

means for heatingthe air is employed at 11,

the temperature of the air between the walls is raised. If it is desired to circulate the air through the various rooms, the dampers 25 in the registers may be opened. If ventilation is required, the damper 19 may be opened sufiiclently, and the air throu h pipes 13 governed by the use of the or inary pipe damper.

Obviously changes in form, construction and arrangement of parts may be resorted towithout departing from the spirit and scope of my lnvention. Therefore, I do not wish to be limited to the exact construction and arrangement shown and described in the preferred form of my improvement.

building having a continuous airspace between the walls, of a hollow top-wall plate having apertures from the hollow portion through one wall of the plate'and communieating with the air-space, a hollow gableend wall plate communicating with the space in the wall plate, a ventilating chim ney, and means near the bottom of the building to permit the passage of air into the continuous air-space. x

2. Thecombination with a double walled building having a continuous air-space between the Walls, of a hollow top-wall. plate having apertures through one wall thereof and communicating with the continuous airspace, a hollow gable-end wall plate the hollow space therein registering with the space in the top-wall plate, a ventilating chimney having pivoted dampers, means to operate the dampers, and means outside of the building and near the bottom thereof to permit the passage of air into the continuous air-space, substantially as shown and described.

In testimony whereof I afliX my signature in presence of two witnesses.
